Methods: From the Traditional Chinese Medicine Systems Pharmacology database, Uniprot database, and Gene Cards database, the relevant chemical constituents information, pharmacokinetic information and hub target of allergic rhinitis were obtained. The protein-protein interaction network was constructed by STRING online database, analyzed and showed by the Cytoscape software. The screened target information was analyzed by the Metascape database for Gene Ontology biological function and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis. Results: Main components of Magnoliae Flos and Xanthii Fructus herb pair, such as aloe-emodin, stigmasterol, beta-sitosterol and Yangambin, depend on the interaction of Nitric Oxide Synthase 3, Tumor Necrosis Factor, Caspase-3 and other functions involve G protein-coupled (amine) receptor activity, RNA polymerase II basic transcription factor binding, protease binding, heme binding, and integrin binding;can regulate calcium signal pathway, serotonergic synapse, Kyoto Encyclopedia of Genes and Genomes signal pathway, tryptophan inflammatory mediator regulation pathway, estrogen signal pathway alone or in combination, and play a role in the treatment of allergic rhinitis. Conclusion: Magnoliae Flos combined with Xanthii Fructus can regulate biomolecular network in multiple targets and pathways to treat allergic rhinitis.展开更多

Method: A549 human lung cancer cells were cultured and treated with different concentrations(5-15 mg/ml) of the ethanol extract of Xanthii Fructus. The expression of mi R-21 and pi RNA55490 was analyzed by Realtime PCR. The proliferation capacity was detected by CCK-8 assay. The anchorage-independent growth capacity was measured by soft agar colony formation experiment. The cell invasion capacity was determined by Matrigel assay. Results: The Xanthii Fructus alcohol extract down-regulated the expression of the oncogenic snc RNAmi R-21, and up-regulated the expression of the tumor suppressive snc RNA pi RNA55490. At the functional level, proliferation, anchorage-independent growth, and invasion capacities of the lung cancer cells were strongly inhibited by the extract treatment. Conclusion: The Chinese herb Xanthii Fructus inhibits the malignant behaviors of lung cancer cells, and the inhibition is largely associated with its ability to change the expression of snc RNAs.展开更多
